To all w/iom it may concern:

Be it known that I, Fnnosnion L. SATTLEY, acitizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new "and useful improvements in Pneumatic Stackers, of which the following is a specification.

- My invention relates to improvements in pneumatic staclrers, and more particularly to the fans therefor of that character designed to be rotated by frictional means and the speed thereof to be changed relatively 'to the speed of its initial driving means .ripheral condition of such driving means ing bracket and adjusting thereby thus preserved and injury thereto avoided; that said driving means may be readily shifted in relation to said'fau to in crease or decrease the speed of the latter as desired; and to improve generally the construction and eliiciency of such fan and adjusting and operating mechanisms associated therewith as will render such arrangement I highly etlicient under all the varying conditions incident to the operation or a threshing or similar machine, as will be hereinafter more fully explained. v 1

' In the accompanying drawings, which are made a part hereof, Figure 1 is a sine elevation of a pneumatic stacker attached to a threshing machine; Fig. 2 a transverse verticalsectional View of a stacker fan, and the operating devices therefor, embodying my invention; Fig. 3 a bottom plan of the same; Fig. i a detail sectional view of the support devices; as seen from the dotted line 4% in Fig. 2; Fig. 5 a plan of the cam arrangement for elevatin the fan-shaft; and Fig. 6 a detail of the" speed changing device.

have shown in oblique position, but which may, he placed in any appropriate position to receive material through its ingress opening, 11, from the separating machine, 12, and discharge the same through a stricken pipe, 13, as usual. '1 he lower portion of said fan-casingt has acentral opening therein, and Within said casingand forming a closure for said opening is placed the fansspider, 15, provided with wings, 16, which spider is preferably coniform in character, as 17, terminating in a horizontal rim or disk, 18, the upper portion, 19, of said spider being tubular in form.

The stud or fan-shaft, 20, is non-rotatable but niovlble longitudinally, and is provided with a collar, 21, hearing against the cone apex, 22, and anti-trictionally mounted in the tubular member '19 by means of roller bearings, 23, (two sets being show divided by a spacing collar 23') secured by a suitable cover or Washer, 24, above which are suitably retained bail thrust-bearings, 25, held therebetween and the retaining cap, 26, which is secured to the upper end of said. shalt by a locking pin, 27, or otherwise, as may be desired. By. employing stud-shaft 20 iii connection with anti-friction bearings such as shown 1 provide a very simple and eliicient axial bearing for the stacker fan, permitting it to be rotated a maximum speed with but little friction at its bearing points, and this is advantageous fon,,as will be readily understood, where the fan and driving shaft are connected in such as geared or frictionally driven fans, considerable strain and friction are present during the operation of the fan consequent upon the en'iployinent of gearing or the limited bearing surface for such to tary shafts, which conditions in my c0nstruction are non-existent, and by which arrangement I obtain a perfectly stable and true bearing for the rotating tan, rendering it very light running and maintained constantly in unstrained and proper position.

Shaft 20 extends through boxing, 30, forming part of bracket, 31, which bracket is secured to frame members, 32, of the' stacker structure, and preferably formed integrally with said boxing is a bifurcated arm, 38; and upon the lower end of shaft 20 is pivoted, at 34, a lever, 35, preferably bifurcated to bear upon opposite sides of said shaft, as at 36, (Fig. 4;), said lever being bossed, 37, and a similar perforation 111 the members of arm 33, sothat these members may be pivot-ally connected (Fig. 2), said lever having an ex "tension or shank, 38, to which is secured an arm, 39, engaging a bolt, 10, which is held by a clip, 41', secured to frame members l2,

said lever-arm 39- being interposed between said clip and a spring, 43, the tension of which spring is controlled by hand-wheel, al As will be readily understood, the fan structure is arrangedito contact. to a certain extent by gravity with its driving wheel, (30, (hereinafter to be more fully described), and also by pressure produced by the action of lever 35, which imparts a constant downwardpull to shaft 20 which, by reason of its c0nnection-with thetan Spider, draws the fan structure downwardly, so that disk 18 while in operation. is in constant engagement with said driving wheel, and as it is desirable under certain conditions to vary and regulate the pressure between these elements I am enabled to readily and etlectively do so' by manipulating hand-wheel, -44, which increases or decreases the tension of spring which inturn acts upon lever 35, through its arm 39, to exert a greater orlesser pull upon shaft 20, with a ccnsequent degree of pres sure upon said driving-wheel by disk 18,

Beneath the stacker fan is driving shaft,

50, which preferably extends across the entire width of the separatingmachine, so that a pulley, 51, may be mounted at either end thereof, and said shaft thus be driven from either side of themachine, as maybe convenient or desirable. Said shaft 50 passes through boxing, '52, tor ning part of bracket a yoke, 70, in ,the groove of hub (56, but,

31, and at each end is rotatably supported in appropriate bearings mounted on the sills Mounted upon shaft 50 isthe driving Wheel, 60, for the fan, of any suitable construction and dimensions for the purpose, that, Which'I have shown consisting of a spider, 61, having a recessed periphery, (32, in which is clamped by bolts, 63, or otherwise secured, any material, (34, which may be adapted for frictional driving el'igagen'ient with the fan structure, said wheel having a balancing hub, 65, splined to said shaftin a well known manner to insure rotation with and permit adjustment lougitiuli'nally of said shaft, a hub, (36, having a peripheral groove, 67, therein formii-ig also a part oi. said. wheel, for a purpos; to be prescntly lescribed. When said shaft 50 is rotated, as will be apparent, said (.lriving wheel 60 is also rotated, and as the latte is in frictional contact with fan-disk 18-, hereinbet'ore descrlbed, said fan Wlll also'be caused to rotate. As a means for shitting wheel 60. I mount which does not inter are with the rotation of said hub, and extending from each side of said yoke is a pair of shifting rods, 71, driven rotatable 't'an embodying a disk I i l i i j l l l l l perforated to register with running parallel with shaft and movably secured at their opposite ends to bracket 72 mounted on sill 53,,said bracket having a shoulder, 73, (Fig, 2), and on said shaft 50 I provide a screw-threaded collar, 74., on the outer end of which is a hand-wheel, 75,- .having an internal screw threaded and peripherally grooved shank, 76, whichis fittedon shoulder 73 of bracket 72, and by which. it'is permitted to rotate but is prevented 't'rou: movement longitudinally of said collar. Said bracket 72 terminates in supporting members, 77, having perforated upturned.

ends, 78, through which the rods 71 pass and behind which they are secured to cross-1neu1- ber, 79, which is fixedly held on collar 7-4:

by nuts, 80, by whicharrangement, when hand-wheel 75 is rotated, collar Tl is caused to travel back and forth on shaft- 50, and through rods 71 and yoke 70 shit"!- driving wheel 60 along said shaft- 50 diametrically across fan-disk-lS to increase or decrease the speed of the stacker-fan as said driving wheel is adjusted on said shalt inwardly or outwardly across said disk, as,

may be desired; and, as said disk 18 may lie somewhat above or flush with the bottom of fan casing 10, in order to prevent contact therewith by-the clamping bolts or other projecting material of driving wheel 60, I

provide an offset opening, as 81 (Fig. 3), 111 said casing, so that said wheel may be slntted to its extreme or peripheral engagement with the disk without danger of con;

tacting with the fan casing.

It is very important that the material on the peripheral surface of driving wheel 60 be protected from abrasion or wear at one portion more than another and thus be coming flattened and unlit-tor use, in other words, thatia true and even surface be constantly maintained, and for this purpose I provide in bracket 31 a ram mounted in cars, 86, which cam is provided with an operating arm, 87, and lies normally out of operative contact with the end of shaft 20.

When the stacker is not in use, and especially when being transported, to' prevent pressure upon andconsequent flattening of that portion of the driving wheel which would normally contact with the disk, I may by impingingsaid pain 85 against shaft '30 raise the same slightly, and with it (by reason of itscollarBl and cap 2(5) the entire t'an. structure from the driving wheel, by which arrangement the tan maintained in elevatcil position away from contact with said driving wheel, and injury to the latter by constant pressure of the fan-disk upon any one portion of itst'riction surface thus avoided.
